UNITED STATES PATENT OFFICE.

ROBERT ROCHESTER, OF DAYTON, OHIO, ASSIGNOR TO THE BARNEY & SMITH CAR COMPANY, OF SAME PLACE.

CAR-S EAT.

SPECIFICATION forming part of Letters Patent No. 595,415, dated December 14, 1897.

Application filed November 2,18'96. Serial No. 610.829. (No model.) v

provement upon the seat shown and described in United States Letters Patent No. 491,7 61.

The objects of my invention are, iirst, to simplify the construction of the seat shown, described, and claimed in said patent; second, to obtain more clearance under the seatrail to better accommodate a system of heating-pipes third, to reduce the travel or movement of the cushion whereby more clearance room is obtained between. the front edge of one cushion and the back vof the seat in front,V

also greater clearance room between the front edges of two cushions when seats are set facing each other; fourth, to detachably connect the rocker with the seat-frame whereby,

when the cushion is removed for cleaning or other purposes, a number of cushions can be l piled up on one another without danger of mutilating the upholstery; fifth, to' provide more simple and efficient means for attaching -the lever-arms to the shafts, and, sixth, to

otherwise reduce the cost of construction of such seats, the manner in which I accomplish these objects being hereinafter fully described, and shown in the accompanying draw# spective view of the rocker; v Fig. 6, a perspective view of the end plate attachable to the wall of the car; Fig. 7, a perspective view from the inside of the seat end adjacent to lthe aisle of thecar detached from the seat; Fig. 8, a like view of one of the back arms with ,connecting-levers and cams attached.

secured to the wall 7 of the car, and the stand 3 is secured to the car-floor. VA wood seat end 8 is screwed to plate 2 and may be of any of l the well-known forms, or it may be made of metal and formed integral with the plate 2 and stand 3. The plates l and 2 are provided with journal-bearings 9, in which the ends of rotatable shafts 10 11 are mounted, on which and near the ends'thereof in proximity to the inside of the end plates arev mounted substantially parallel lever-arms 12 13, arranged in pairs and about equal in length. These arms are each provided with a hub 14, having a cam 15 and a projecting lug 16. These hubs are preferably cast on a core and with a longitudinal slot 17, extending acrossthe edges of the lever-arms, the object of which is to avoid the necessity of boring the hubs to fit the shafts, which, as a matter of economy, are made of ordinary gaspipe, which varies more or less in size, and by casting the hub with a slot,as described, and using a core of slightly less diameter than that of the pipe as it usually runs the hub, which by preference is made of malleable iron, can be driven onto the pipe, the slot permitting it to spread or enlarge its diameter to suit the pipe, and thus la tight fit is obtained without the f employment of machine labor and in a very inexpensive manner. When the hub is driven to place on the shaft, it may be riveted or otherwise additionally secured. The top side of rails 4 5 are inclined toward the center of the seat and carry at each end arocker IOO 23, and arms 2i 25, through which opening the hubs 1-t rotate by the movement of the seat-back 26, which is provided with arms 27 and to which the lever-arms are pivoted at 2S. The rockers are held in line by guides 29, formed on the sockets G, and the projecting lugs 1G, formed on the hubs 11, which lugs are so arranged as that one of them will at all times bc in proper relation with each rocker to prevent lateral displacement of the same.

The function of the arms 24 25 is to prevent the upward displacement of the rockers while the cushion-frame 30 is being removed, and the latter being supported on the rockers is held in position by the projecting pins 20, which engage holes 3l in the bottom of the cushion-frame, by which arrangement the latter can be easily and quickly removed and replaced by one man, while in the seat of the patent to which I have referred two men are required to remove or replace the cushion, owing to the difiiculty experienced in adjusting the rockers (which in said patent are described as runners) to their proper positions in consequence of their being secured to and removable with the cushion-frame; and as in cleaning cars it is the usual custom to remove all the seat-cushions and pile them up in a convenient place where they can be drubbed or otherwise renovated it is essential that there be no projections of any kind about the cushion-frames to interfere with piling them compactly or to cause mutilation of the upholstery, and it will be observed that by detachably mounting the cushion-frame to the rockers in thc above-described manner I obviate all danger of injuring the upholstery by piling the frames one upon another.

To the inner edges of the rails 4 5 and at some distance from the wall end of the seat are suspended hangers 33, which support the ends of foot-rests 34 35, the opposite ends of which are supported bythe stand 3 in the usual manner, the object in locating the hangers 32 33 away from the wall being to provide sufficient space for a system of heating-pipes to extend longitudinally of the car against the wall thereof, and as it is desirable to have as much space as possible under the center of the seats to accommodate lateral pipes, which are frequently extended from the longitudinal heating system, I have reduced the length of the cams and all other parts likely to interfere with such pipes to a minimum and have also thereby reduced the forward-andbaekward movement of the cushion-frame caused by the shifting of the seat-back, thus gaining room between the seats in whichever position they may be set, still retaining the. necessary relative position of the cushion and back to be comfortable for the occupant of the seat without increasing the space required in which to reverse the back.

Then the seat-back is in either of its two normal positions, as shown in Fig. 1 and by dotted lines in Fig. 2, the ends of the rockers are at rest on the inclined surfaces of the rails 4 5, and in order that the shifting movement of the back and cushion may bc the more clearly understood I will now describe it in reference to Fig. 2 of the drawings. IVhen the back is shifted from the position shown in full lines to the one shown in dotted lines, or vice versa, the movement of the leverarms 12 13 will cause a partial rotation of the two shafts 10 11, thereby oscillating the cams 15 and projecting lugs 1G, and when the back is in the position shown by full lines the cams attached to the rear shaft 10 impinge against their cooperating ears 21 of the rockers, and as they are rotated by the shifting of the back the two rockers will be moved down the incline of rail 4 and will ride upward over the inclined surface of rail 5 in the opposite direction to that of the movement of the back, and. vice versa, and thus cause the cushion to extend beyond the seat-rail on the front side and simultaneously ride upward at the same side into an inclined position, tending to add greater comfort to the occupant. The movement of the back is limited by the sockets (S, which, in addition to the function already ascribed to them, act as stops for the lever-arms 12 13 to strike against when the back is shifted from one of its normal positions to the other and by which further downward movement of the back is arrested. Various other forms of stops may be employed for the purpose, but I prefer the one just described, on account of its simplicity and economical advantages.

In the foregoing I have described only such detail of operation and construction as I have deemed necessary to clearly explain my invention in connection with the seat of said Patent No. 491,761; but it is obvious that my improvements are applicable to seats differing in structural detailfrom the one described and claimed in said patent, and therefore I do not wish to limit my invention to such exact construction.

I'Iaving thus described my invention, I claim- 1. In a car-seat of the class described, the combination of a frame, consisting of a pair of end plates having sockets formed thereon, and a pair of rails, the ends of which are held in said sockets, a pair of shiftable rockers, a detachable cushion-frame carried by said rockers, guides formed on said sockets to rctain said rockers in line, a shiftable back, mechanism connecting said back with said rockers, whereby the latter is shiftable horizontally of the seat by the movement of the former, and arms formed on said rockers to prevent their displacement when the cushionframe is removed, substantially as set forth.
